I made a tuck shop at home.  I picked out items to sell and created my own price list.

I then opened the shop up to customers (my family).  They were to pick one item and then pay using a £1 coin.  I then had to work out how much change they would get back.

I used the ’empty number line’ method to work out their change.  After doing this a few times I became more confident and could then use this method in my own head.

I then extended my shop, adding more items and creating a new price list.

During this game the customer was allowed to pick a few items.  I then had to add them up to see how much the total cost would be.  To do this I separated the numbers into tens and units to make the addition part easier to visualise.  Again, this process became easier in my head after practising on paper first.

There are so many strategies we can use to add and subtract.  See how many you can use for this task.  You might have a favourite method.  Let your teacher know it! 😊
